Powder batches of pharmaceutically-active particles and methods for making same. The pharmaceutically-active particles have a small particle size and a narrow particle size distribution and are particularly useful in devices such as medical inhalers. The present invention also provides an aerosol-based method for producing pharmaceutically-active particles wherein an aerosol is produced having a tightly controlled droplet size to produce pharmaceutically-active particles having a small particle size and narrow particle size distribution. |
